These are the fees that utilities collect to cover the costs associated with assessing the impact of connecting Powerwall to the electricity grid and potential meter upgrades.  These fees vary substantially throughout the country.

That depends on a number of factors: How much you pay for electricity, whether those rates vary based on the time of day, whether your utility allows you to feed excess energy back to the grid and be compensated for it, and whether solar is included.  We will work with you to make sure that the system is setup to suit your needs and where possible, reduce your electricity bill.

Installation of a Powerwall may impact your home insurance. We recommend that you contact your insurance company to discuss.

Some utilities offer net metering programs where a credit is given to the customer for exporting power back to the grid. Our installers can help you determine what is currently available from your local utility.

We typically recommend that Powerwall be installed close to your main electrical panel. Indoor, outdoor and garage installations are possible. Your Certified Installer will work with you to determine the ideal location for Powerwall installation on your property.

Powerwall should not be installed in habitable areas such as kitchens and bedrooms.

Yes, requirements vary based on the electric utility and regional safety authorities. Your Certified Installer will advise you of local requirements and facilitate the application and approval of any permits that are required.

Upon acceptance of the quotation, your Certified Installer will initiate the utility connection application process and arrange for all the necessary permits. This process can take 4-8 weeks depending on project complexity. Installation of equipment is usually complete within 1-3 days depending on project complexity. Final inspection by local safety authorities may be required prior to commissioning your Powerwall.

Yes, Powerwall is rated for indoor and outdoor installation with an operating temperature between -20°C to 50°C (-4°F to 122°F).

Powerwall must be installed vertically on a level floor or an upright wall that can support 136 kg (300 lbs) which is the maximum weight of a single Powerwall.

Powerwall can be installed on most surfaces as long as the wall or floor can support the necessary weight (136 kg/ 300 lbs). 

The unit must be installed upright and is designed to be wall or floor mounted.

A single Powerwall requires approximately 60" x 36" of wall space. Additional space will also be required for associated equipment. Your Certified Installer will work with you to identify a suitable installation area in your home.

This is not recommended but is possible. Removal/relocation of the unit is costly, may cause damage and may void the warranty.  If you would like to make changes to the location of your Powerwall, please contact your Certified Installer.

The availability of Tesla Solar Tiles in Canada is uncertain at this point in time. Please check back here for updates.

Powerwall comes with a 10-year warranty but is expected to outlast its warranty period.

It must be connected to the Internet to allow remote firmware upgrades from Tesla. If an Internet connection is not established or is interrupted for an extended period, and Tesla is unable to contact you, the warranty may be limited to 4 years.  

Powerwall needs internet (wired Ethernet and your home Wi-Fi) or cellular service to communicate with the Tesla mobile app and receive software updates.  A reliable connection is required to provide new product features over time.  Powerwall can function if the connection is temporarily lost but should not be installed in a location without internet or cellular service.

Tesla’s lithium ion batteries, such as those used in Powerwall, contain valuable materials that can be recovered and recycled for further use in both battery and other applications. Tesla strongly encourages recycling and attempts to retrieve all batteries that have reached end of life (EOL) for purposes of recycling. 

Please contact MPOWER or your local Certified Installer if you would like to replace or dispose of your old Powerwall.

The integrated inverter in Powerwall is covered under the 10 years warranty. Powerwall must be reliably connected to allow remote firmware upgrades from Tesla. If an internet connection is not established or is interrupted for an extended period, and Tesla is unable to contact you, the warranty may be limited to 4 years.

Powerwall is currently available in white.

A single Powerwall can keep most essential items such as lights, fridge, well pump, furnace fan and various household electronics operating for 12-24 hours during an outage. Adding a second Powerwall will double how much energy you can store and use. During a power outage, that means your essential appliances will last twice as long. It would also allow you to store twice as much solar energy during the daytime for use at night.

Tesla Powerwall 3 uses lithium-iron-phosphate (LFP)  cells.

Lithium ion batteries in Powerwall have several advantages over lead acid batteries.  Lead acid batteries typically last 5-7 years and can only be partially discharged.  We call this the depth of discharge and for lead acid batteries, it typically ranges between 50-70% of the total capacity.  Powerwall has a 10-year warranty and offers a full depth of discharge (0 to 100%). 

Some lead acid batteries also require maintenance, are bulky and often need to be installed in a special enclosure.  In comparison, Powerwall is a sleek wall mounted unit that requires no maintenance.

Powerwall provides clean, quiet, maintenance free energy with automatic backup power that provides enough energy security for most common outages.

Gas generators are noisy and produce noxious fumes so they need to be located outside.  They take between 20 seconds to 3 minutes to start-up.  Powerwall has nearly instant power (1/4 second), no emissions and a quiet cooling fan.

Gas generators require periodic test starts and cleaning.  Powerwall does not require maintenance and comes with a 10-year unlimited cycle warranty.

If you have already invested in a generator, installing Powerwall can seamlessly ride through regular outages and allow you to experience most of the daily benefits. The generator would run less frequently and get through abnormally long outages if the upfront cost of several Powerwalls isn’t feasible.

Backup generators are typically loud and require regular maintenance and/or refuelling.  
Powerwall provides homeowners a smaller, quiet and automated emergency power supply during a blackout.  When paired with solar panels, the power is clean and renewable which minimizes negative impacts on the environment.

If you have a new or existing microFIT contract, you are allowed to install a battery storage system that is independent of the microFIT facility on your property.  Connecting a battery storage system within your microFIT facility will be a violation of your microFIT Contract.  Your MPOWER Certified Installer will work with you to determine if Powerwall would be permitted under the terms of your contract.

Yes! Solar panels harness the sun’s energy and convert it into energy we can use in our home.  Connected with a Powerwall, you will be able to store the excess power your solar panels produce in your home and use it when you need it most.  Your MPOWER Certified Installer will be able to install solar panels along with Powerwall.

Yes, Powerwall can be integrated with your existing solar system.  Powerwall is compatible with solar inverters from SMA, SolarEdge, Fronius, Enphase micro inverter, Delta, and ABB.  Tesla will continue to explore compatibility with other inverter companies.

Net Metering allows customers to feed excess energy back into the grid.  Excess energy fed into the grid is credited to your account to reduce your electricity bill.  Check with your utility to determine if net metering is available in your area.

Powerwall does not currently have the ability to charge from a generator.

If you have an existing generator connected to your property and would like to install Powerwall at this time, the generator must be completely isolated from the Powerwall on a separate electrical panel.  The generator cannot be allowed to feed energy into Powerwall.

Your MPOWER Certified Installer will work with you to ensure the system is properly configured.

Yes, Powerwall can provide stored solar energy to your EV through your home electrical panel.

Note that a fully charged single Powerwall has 13.5 kWh of capacity and a Tesla Model Y has 60-75 kWh of capacity.

Many electric utilities provide usage reports on the monthly bill or provide internet access to usage reports.  There are also several third party power monitors available for sale that will assist homeowners to measure electricity usage at the appliance and fixture level. Your local Certified Installer can also perform an energy audit if needed.

A single Powerwall can support up to 20kW DC of solar. Depending on your electrical needs and roof size your local Certified Installer will work with you to determine the optimal configuration. 

Every time you convert energy from AC to DC, or DC to AC, there is some energy loss.

Solar to battery to home/grid efficiency is 89%.

Solar to home/grid efficiency is 97.5%.

Fridge, freezer, furnace fan, well pump, essential lights, internet modem/wifi router, outlet for phones and laptops, a television, and security system are all examples of appropriate loads for a single Powerwall to back up during a power outage. Multiple Powerwalls are typically required to provide whole home backup for more than 24 hours. Your local Certified Installer will assist you with configuring the system that meets your expectations.
